A laundry apparatus includes a tub, a drum, a control unit, a motor, and a dynamic balancing assembly. The drum is positioned within a fluid containment envelope of the tub and rotatable relative to the tub about a primary rotation axis. The motor is coupled to the tub and operatively coupled to the drum to cause rotation of the drum. The dynamic balancing assembly includes an orbital balancing passage arranged concentrically around the motor, a first counterweight device, and a second counterweight device. The first and second counterweight devices are positioned within the orbital balancing passage and are responsive to the control unit to move the first and second counterweight devices along the orbital balancing passage to adjust an angular position of the first and second counterweight devices. A cross-sectional plane passes through the dynamic balancing assembly, the motor, and the fluid containment envelope of the tub.
